Origin Story
战国时期，著名的思想家荀子在《富国》篇中强调，一个国家要富强，必须重视农业生产，增加国家的财富，同时也要节俭，避免浪费。他认为，只有做到开源节流，才能让国家富裕，百姓安居乐业。故事讲述了一个勤俭持家的农户，他一方面努力耕作，增加粮食产量，另一方面精打细算，节省开支，最终过上了富足的生活。这个故事生动地诠释了开源节流的重要性，也反映了古代中国人民勤俭节约的传统美德。 在那个时代，农业是国家经济的支柱，增加粮食产量是开源的重要途径。农户们辛勤劳作，改良耕作技术，改进农具，提高单位面积产量。同时，他们也注重节约，减少粮食的损耗，避免浪费。例如，他们会仔细保管粮食，防止虫蛀鼠咬，还会将剩余的粮食制作成各种食品，以延长保存时间。 此外，他们还会在日常生活中节约用水用柴，尽量减少不必要的开支，避免铺张浪费。这种勤俭节约的生活方式，不仅保证了家庭的经济稳定，也为国家的富强做出了贡献。
During the Warring States period, the famous thinker Xunzi emphasized in his essay "Rich Country" the importance of agricultural production for strengthening a country, both increasing national wealth and saving and avoiding waste. He believed that only by increasing revenue and reducing expenditure could a country become prosperous and its people live in peace and prosperity. The story tells of a thrifty and resourceful household that, on the one hand, diligently worked to increase grain production, and on the other hand, carefully calculated to save expenses and ultimately live a prosperous life. This story vividly illustrates the importance of increasing revenue and reducing expenditure and reflects the traditional virtues of thrift and saving in ancient China.
